Suitable for various types of concrete such as those for summer use, large volume, and pumping. It reduces water usage while maintaining slump, allows for on-demand retardation, enhances strength, saves cement, reduces hydration heat, and improves durability and pumping performance.
Ⅰ. Product Standards
Complies with GB 8076-2008 "Concrete Admixtures" standard.
Ⅱ. Application Scope
1. Weather & Supply: Ideal for hot-weather concreting and ready-mixed concrete (RMC).
2. Special Structures: Suitable for mass concrete, lean concrete, and cast-in-place bored piles.
3. Construction Methods: Applicable for slip-form construction, pumped concrete, and mineral-admixture concrete.
Ⅲ. Performance Characteristics & Technical Specifications
1. Safety: Non-toxic, non-flammable, non-corrosive, and maintains stable morphology.
2. Steel Protection: Contains zero or negligible chlorine ions, ensuring no corrosion to reinforcement bars.
3. Low Alkali: Na_2SO_4 \le 18\%. Low alkali content prevents Alkali-Aggregate Reaction (AAR).
4. Workability & Strength:
Water Reduction: \ge 10\%. Significantly increases flowability with a slump of 180mm–220mm.
Slump Retention: Minimal to zero slump loss over time.
Strength Boost: Increases 3-day strength by 20%–35%, 7-day by 15%–35%, and 28-day by 10%–30%.
Cement Saving: Saves 7%–20% of cement while maintaining constant strength.
5. Setting Time: Extends setting time by 2–15 hours (or longer). Retardation can be customized through testing based on client requirements.
6. Pumpability: Air content < 4.5%, improving workability for easier pumping.
7. Durability: Significantly reduces the heat of hydration and delays the exothermic peak. This helps control thermal cracking, enhances density, and improves long-term durability.
Ⅳ. Recommended Dosage
Powder: 1.0% – 4.0% of the total cementitious material weight.
Liquid: 1.5% – 4.0% of the total cementitious material weight.
Ⅴ. Instructions for Use
Optimization: The specific compatibility and dosage should be determined via trial mixes according to project materials and requirements.
Ⅵ. Addition Method
Liquid: Typically added with the mixing water. For better results, add later in the mixing process or stir in just before pouring.
Powder: Add directly into the mixer with the binder. Extending the mixing time slightly is recommended for optimal performance.
Ⅶ. Packaging, Transportation & Storage
Packaging:
Powder: Double-layer packaging (inner plastic liner, outer woven bag), 25kg or 40kg net weight per bag.
Liquid: Available in drums or tanks.
Logistics: Protect powder from moisture/bag breakage during transit. Ensure liquid containers are sealed to prevent leakage.
Storage:
Powder: Store in a ventilated, dry warehouse. If clumping occurs due to moisture, it can be used after passing a 0.63mm sieve test to re-determine the dosage.
Liquid: Store in a cool, dry place; avoid prolonged exposure to direct sunlight.
Shelf Life: One year. Product may still be used after the expiration date if it passes re-testing.
